Microprocessor Controlled Converter-Fed Synchronous Motor Using Subtransient Flux Model

Abstract A digital control system has been investigated for converter-fed synchronous motors particularly in high power applications. Improved system ruggedness is ensured using subtransient flux reference synchronization. A simplified model of the converter-fed synchronous motor is studied and the optimal torque performance is determined. The proposed microprocessor-based control system is discussed in detail. Transient behaviour of the system is tested experimentally.
